Many of his detractors might point their fingers at Justin and wonder why he doesn't just make better decisions, but it may not be that simple!!

See, addiction can be hereditary and drug & alcohol abuse run in the 19-year-old pop star's family!!!

His mother Patti Mallette has spoken out about her childhood and about how she had major problems with drugs and booze way before her son was even born! Yup, the very same mom who may be involved in the current prescription pills scandal!

Apparently she started drinking when she was 14 and got mixed up with drugs when she was only 15!

OMG! That's so young!

At one point her life was so bad that she even attempted to kill herself!!

Patti admitted:

“It was a culmination built up over the years of the abuse and the pain. At the time I was messed up with drugs and alcohol and in a depression.”

Justin's dad Jeremy Bieber, who was with him in Miami this morning, may have battled drug issues, too. A judge apparently once ordered him to stay away from his son when he was under the influence of alcohol and non-prescription drugs.

Ugh! That's so sad!!!

Do U Justin's family's history of substance abuse is a contributing factor everything that went down today? Weigh in (below)!

Justin Bieber is the reason for his recent behavior. I get being in a household with an alcoholic/drug addict makes a person more likely to repeat the bad behavior but I grew up with an alcoholic/drug addict and I made the decision to never be like that person. Justin Bieber has a bad support system who has clearly never told him no and let him get away with anything he wanted. That's the only reason someone would go from how he was when he first broke onto the scene to now. He feels entitled to things he shouldn't be and feels like he's untouchable. Hopefully this recent incident sticks and he gets serious consequences for his DUI

This family is a product of 'Ontario Housing' - goernment subsidized welfare bums ! They take advanatge of Ontario's gernerous welfare and housing allowances, and stay at home and do drugs and drink……really ! Google Ontario's genrous welfare policies, and see how people like this Bieber/Mallette TRASH just exist on government hand-outs….the word 'work' is not part of their vocabulary ! WHITE TRASH !

He's not a drug addict. He uses weed and alcohol but is not dependant on them. The problem is his attitude and the fact that he has been allowed to do whatever he wants with no boundaries. Rehab or therapy is the only solution now.

I'm so glad you posted this. I a lot of people don't realize the kinds of stuff Pattie went through when she was younger…that can't be easy for him to process along with everything else teenagers go through. She even talks about being molested as child in her book. People only see the money and the fame and expect that to be a cure all but it's not. We have seen that so many times with lots of celebrities. All we can do is hope that with therapy and maturity Justin will rise above this. People can talk shit about him as an artist but he is very talented and he's proven that. His last "album
' is perfect and most people haven't even heard it.
Anyway..that's my JB rant for the day.

everyone can ya please just leave Justin Bieber, he hasn't done anything to you guys or anyone so get over it. it is his life not any one else`s like seriously u all need to leave him alone or just grow the fuck up and get over it!

And I have met him more then once and say one thing he is a nice guy and it is HIS FUCKING LIFE AND LEAVE IT AS THAT AND IM A BIEBER AND I AM HAPPY TO BE AND DONT JUDGE ON PEOPE YOU DONT KNOW
